Title: Device for driving linear image sensor
Inventor: ARIMORI IWAO
IPC: H04N1/04
Filed: 1990-10-05
Abstract: PURPOSE:To read out a distortion less image from the start of subscanning over a wide range by connecting a spring for assisting acceleration at the time of starting subscanning to a carriage. CONSTITUTION:The spring 21 for assisting acceleration at the time of starting subscanning is connected to the carriage 3 mounting a linear image sensor 4. When the carriage 3 starts subscanning, the carriage 3 is suddenly accelerated in the subscanning direction by the force of the spring 21 and quickly drawn. Thereby, the image sensor 4 also is quickly driven in the same direction, a distortion less image can be immediately inputted. Since the length of the spring 21 is short, excess acceleration is not applied to the carriage 3, the operation of the carriage 3 is stabilized and the initial input image data can be outputted form the image sensor.

Title: Semiconductor laser
Inventor: MITSUNARI TOSHIHIRO
IPC: H01S5/00
Filed: 1987-10-22
Abstract: PURPOSE:To prevent peeling off of electrodes by constructing an activated layer on a semiconductor substrate of a multilayer structure in which such activated layer is interposed between clad layers whose forbidden band widths are larger than those of the activated layer, and an impurity diffusion region in a region where the thickness is thin at the topmost of the activated layer. CONSTITUTION:After epitaxially growing a clad layer 6, an activated layer 5 whose forbidden band width is smaller than the clad layer 6, a p-clad layer 4 and an n-cap layer 3 sequentially on an n-type semiconductor substrate 7, a part of the n-cap layer which is a region to be formed into an electric path by impurity diffusion is removed to a predetermined depth, and an impurity diffusion region 9 is formed on the n-cap layer 3 by forming an oxide film having an aperture in such region and diffusing it. Since the thickness of the n-cap layer 3 in the part of the electric path is thinner compared with other parts of the cap layer 3, an impurity diffusion region 11 remains within the cap layer 3 when the impurity diffusion region 9 reached the clad layer 4, whereby the electric path is restricted by the impurity diffusion region 9 and the current constricting structure can be maintained. According to the constitution, the oxide film is no longer necessary, thereby preventing the peeling off of the electrodes.

CONSTITUTION:The first amorphous SiO2 powder prepared by hydrolyzing Si alkoxide and having 0.5-10mum particle size is blended with the second amorphous SiO2 powder having <=0.1mum particle diameter and contained at a mixed ratio of <=80wt.% to afford mixed amorphous SiO2 powder. 30-100 pts.wt. water and 0.3-5.0wt.% dispersing agent such as polycarboxylic acid ammonium salt are added to 100 pts.wt. of the resultant mixed powder and further 0.5-10 pts.wt. water-soluble gelling agent such as ammonium alginate or NH4NO3 is added to the mixture to form SiO2 slip. Then the SiO2 slip is poured into a mold and gelatinized and cured and then taken out and dried at 4i40% relative humidity. Then the gel is heated at 900 deg.C and defatted and then sintered at 1200-1700 deg.C to provide the transparent quartz glass in high yield.

Accordingly, for the coefficients of linear expansion at room temperature GaAs is 6, Au 14.2, Si 2.6, and C 3.1, so that any stress between the substrate 1 and the PHS7 is moderated and hence the chip is reduced in its deformation. Thus, the chip can be made large-sized without deterioration of heat radiation characteristics.

Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent pre-ignition by controlling a variable valve device. SOLUTION: Pre-ignition is measured (S1), and when judgement is such that the pre-ignition exceeds the specified level (S2), the target open overlap amount of the suction/exhaust valve is calculated in shrinkage from the normal (S3), and the target closing timing of the exhaust valve and the target open timing of the intake valve are calculated so that the target open overlap amount is obtained (S4), and a valve drive device is controlled so that the exhaust valve is closed in the target closing timing and the intake valve opens in the target opening timing (S5). Thus, blow-through of the combusted gas from the exhaust passage is suppressed, and the residual quantity of high temp. combusted gas is decreased so as to decrease the intra-cylinder gas temp. near the upper dead point in compression, and thus pre-ignition is avoided.
